Does the strength of the electromagnetic field of a coil depends upon the thickness of the wire? Answered

Whenever I have problems with the magnetic field strength of an electromagnet people tell to use a finer wire, I have some, its thickness is not more then the thickness of a hair, but whenever I use it, I have difficulty in connecting it with the battery because it's so thin it easily breaks off, and when I turn on the switch, it burns up instantly, maybe I am not using enough length of it. So does the field strength really increase with the decrease in thickness of the same length of the wire and same diameter of the coil, if it does than why?

Help with wooden bathroom sink cabinet top surface

Hi, I have just relocated to Switzerland and live in a rented accommodation. The master bathroom has double sink wooden cabinets. Unfortunately, the top surface of the cabinets is not covered by glass, marble, or quartz. The sinks sit on the surface (solid wood). No matter how careful someone might be while hand washing etc., you can't get away without splashing. Major stress if you think that you might need to pay for replacement of the cabinets at the end of tenancy.How could I protect the area? Many thanks PS. (link) Master Bathroom sink top pictures

Classroom Organization

Back to school is quickly approaching, which means teachers are heading back to set up their classrooms, unpack and reorganize books and supplies, and start planning for the new group of students. If you're like me, then you are also redesigning your whole classroom furniture layout. ;D Every teacher I know seems to have a system, so I thought it would be fun to share our favorite tips and tricks for keeping it all organized.Do you use baskets and bins or folders and binders? Paper calendar or all digital? How do your students turn in their work? Mailboxes, hand-made sorters, or letter trays for each class period?How do you show off student work? Do you use student portfolios, bulletin boards, a hanging space, or the classroom windows?What about: Lesson Plans The Class Library or Guided Reading Area Math Centers STEM Resources Classroom Jobs Substitute Teacher Plans Table CaddiesThis is also a great opportunity to get inspired and plan your project ideas for the Classroom Organization Challenge that starts August 5th. :D

Coin a phrase, or one liner

Have you ever wonder were, phrases come from like  " That's what she said " or  "See you later.......not if I see you first" or "Well, there's your problem!" I think i may of coined a phrase, but of course I can't prove it  " Its funny cause its true"   I even heard it on TV the other night, I have been saying that for years. Anyways today after a student made a mess I gave him a mop and bucket and told him to clean it up. After 20 minutes I came back and he had managed to make the mess about 100 times worse. I was very annoyed with him and I was inspired to say  "Never send an idiot to do a job a monkey could do" Anyway there is, If it takes off I will now have proof that i said it first on 20 april 2016 So whats your favorite phrase or one liner?  Maybe you could come up with the next "That's what she said!"

Help: hacking fog machine with timer relay

Hello, everyone. I need a little help! I'm not very skilled in circuits, but I have already did something similar with a different device (following some tutorials from instructables); this time the same approach seems not working.I have a sensor which triggers a timer relay; when the relay is triggered on i would like to switch on my fog machine (which is already turned on and heated) and spread the fog until relay reset.From the relay I have a COM and the NO(/NC) output.I need to connect those outputs to my fog machine cable controller (which i cannot unmount completely). I attach here some photos of my circuit.The first image shows a red area (short circuit!), and two green areas (fires fog): if i connect the relay output there (COM or NO or NC) circuits reacts even if the relay is off.I have tried connecting the relay out to blue/white wires but nothing happens.What can i do? I'm starting to think to connect only NO (or NC) to both blue and white wires. Any help is appreciated.Thank you so much.- - - - - EDIT - - - - -Thanks for the first 2 replies: connecting COM and NO to blue and white cable was the first thing i did, but with no success. I tried again (maybe i was doing wrong), but again no success. I add 4 new pics of the circuit from above (i have dismounted it). Hope it is much clearer now.Thanks again for your support.

Some of the current Ebay and Paypal scams to be aware of

Recently the spam activities increased for my inbox and with that the amount of phishing Emails and direct scams.Today I will only focus on the big two: Paypal and Ebay.1. General Paypal scams and phishing mails....Most of these are really easy to spot.Genuine Emails coming from Paypal always address you with your full name!Scam or other bad Paypal Emails will use your Email address or just your first name.There is a problem with some users here, but I will go into these details a bit further down.In most cases the scammer will spoof areal looking Paypal Email or server address.This means in your Email client the sender appears as "Paypal" and not some cryptic server address you can find in the source code of the offending mail.The simple scams use links to malware or phishing sites - often trying to look like the original so be aware of this.2. The latest and for some hard to spot Paypal scam.You are more likely to become a target if the Email looks genuine enough to fool you to click on some link in it.A lot of users do a quick check with the mouse on some links offered and check in the bottom left corner for the link that appears.Sadly in the latest scam mails the scammer uses genuine graphics and links.In some case directly from the Paypal servers, like logos and backgrounds.Only one link is in there that will fool you.If the scam informs you about a payment you supposedly made than it will be the link directing you to your account to cancel the payment for a refund.If the scam mail is about a refund you got then it is the same link - the one making it easy for you to get to your account settings.In one scam mail I landed on a really good looking copy of Paypal's login portal.The address bar however did not contain the usual secure HTTPS and neither a genuine address going to paypal.Problems with these new scam mails happen if you follow the suggestions or free will for naming your Email account.If your Email is for example tommy19726@mymail.com then you will spot this quite easy in the scam mail when you are addressed as tommy19726 instead of Tommy Hilfinger.It seems to be a favour now to have a real looking Email, so Tommy might have used Tommy.Hilfinger@mymail.com.And then in the scam mail he would be addressed as "Tommy.Hilfinger" - only the DOT is then different to a real Paypal mail!!!If you have one of these Email addresses with no numbers and just your first and last name then pay specail attention when checking Paypal mails!!!3. The latest Ebay scam from China :(Lately I had to order quite a few things that I could only get through Ebay for a reasanable price.Shipping costs were the major problem with other sources as I don't see the point in paying much more for postage than for what I bought.Anyways, the scam goes like this:You order something with a value above about $50.You get the usual payment confirmation and a few days later a tracking number.Problem is that this tracking number won't get any updates at all.It usually only states "Shipping information received".This means someone in China requested a shippment but never actually lodge an item or had one picked up.You can't do anything through Ebay until the max delivery time is over.Trying to get a working tracking number from those seller only gives you excuses but nothing of use.In many cases the answer you get has no relation to your request!Once the last date to get the shippment is over the seller keeps stalling and asks you to wait a few days more.No attempt to explain that the tracking shows that nothing at all was sent on the way gets any useful answer.It is like talking to your digital assistent set to a language you don't speak.Once you start a claim through Ebay the case and refund is handled quite quickly.Does not mean you are left alone by the seller, especially if you did the right thing and left negative feedback.And no surprise, suddenly the seller is then even able to uderstand your language LOLBiggest thing is that these dodgy seller are adjusting quickly.Once you state in your responses that you will open a calim they usually "offer" a refund.Even if you clearly state you want the item and not the refund you will get a nice thank note back and then a refund that makes a claim impossible.You are left with no item and can wait another 3 or 4 weeks if you find trustworthy seller that is.Only chance is to open a "Item not received" claim right after the last due date.But even if Ebay agrees and provides you with a refund, as they have no interest to do more, you need be quick!The item in question will end in the hidden section of your purchase history.Only if enable to show your hidden items you can then select it to rate at least the transaction for a negative feedback.If you act quick enough you can even leave negative feedback in the usual way, but only through activating your hidden items.What can you do to stay secure?The easiest way for Paypal is to simply ignore all content in any Email you get that seems to be from Paypal!Whatever you do or feel you need to check: Go directly into your Paypal account through the app or with your browser but DO NOT use any links provided in any Email.If you think an Email is suspicious then just forward the Email to "spoof@paypal.com" - or .com.au for Australia, .de for Germany and so on.In case the Email is genuine you will get a corresponding response.If the Email is indeed fishy then Paypal will notify you to delete the Email in question.For Ebay the problem is not s easy - at least if you don't buy locally.From my end I can only state it is the Chinese sellers, Hong Kong and mainland.And a few years back the recommendation was not to buy from a seller with less than 95% of positive feedback.You can try it yourself and mess up one sale if you are private and see how badly your feedback goes down - just kidding, please don't try!!!With the introduction of "power Sellers" and Ebay stores however this guide was rendered totally useless.A power seller with 99.7% positive feedback can still literally have hundrets of negative feedback comments for the past few months.Quite often you see it spiked a month or 6 ago - a clear indicator the seller is going to new account and tries to make as much quick money as possible before Ebay closes him down for good.If in doubt you really need to check the negative feedback in detail before buying.Some really dodgy sellers make all sales "private".This not only removes the item from the feedback but also the sale price.Intended only for special uses, Ebay sees no need to stop this misuse.If you can't see detailed feedback for a seller then just don't trust the seller!If you see way too many negative feedback comments during the past 6 months then stay away!Click on other listing showing identical listing images and you can be almost certain that even if the seller name is different it will be the same scammer.You can usually confirm this by seeing a similar pile up of negative feedback with that seller.Why do I stress so much about Ebay scammers if you get a refund anyways?Interest...No really, I mean interest in getting it for the money in your account.Firstly, if you wasted about 100 bucks and waited a few weeks for finally getting a refund, then you were out of pocket twice.Once by paying for something you never got and then again for the money you lost in interest.Sure on your end only a few cents worth...But see it from the other side:Have just hundred transactions of $50 going into your Paypal account where you never actually bother to send anything.Add a longer than usual shipping time and make it free.Means you have $5000 in your account collecting interest rates for 4 to 6 weeks.Do it on an even bigger scale and you can invest 10.000 or more on a regular base.With up to 10% of interest on foreign currency Chinese banks are only too happy to take it.Or did you never wonder why an item sold in Greece needs to be paid for in US Dollar, UK Pound or Canadian Dollar? ;)A good Ebay scammer can make over $25.000US in interest rate payouts this way before Ebay even decides to limit or monitor his sales.And once Ebay or the feedback rating goes to negative on him it continues on another account with the same items and availbilities.Quite often you can find a seller has let's say 5 items sold and 12 still available.Isn't it then funny and of course pure coincidence that another seller has the same, hard to find item, with the exact same 5 items sold and 12 available?Ebay has no interest to actually stopping this in any way, Paypal also prefers to look away if the same account is used for multiple Ebay accounts.Not even the need to provide the Paypal details of the seller in plain english is a requirement anymore.You need to use a translator to figure out what "company" is behind the Paypal account and it never matches the Ebay account in any way....I did some checks on the few suspicious sellers that still had at least item prices listed with their negative feedback.There are some out there having a vlue of well over $12.000US in "not received" claims over the last 12 months.About a year ago I tried to start a little (ad sponsored) reporting service online.Scammed Ebay users were asked to provide the details about the item, Paypal address of the seller and the amount/time until refunded.Within 3 days of going online and with only having two users that reported a scammer my provider gave me a shut down notice - effective immediately.A few days later I got an Email stating my website was shut after both Ebay and Paypal stated I would violate their privacy terms and break US law.Needless to say this notice also included a note informing me that if I attempt to conitnue to provide such service I will be taken to court for legal action.So what was the fuzz all about you might wonder?It was planned that users can provide the required data, without this data actually showing up anywhere.Once the databse was full enough a user could enter a seller or shop name or even a Paypal account to have it checked for negative things.You either get "unknown" or a list that states when and how many users reported this seller.With no deatils about any transactions, item numbers or user names linked.Did I mention how supportive Ebay and Paypal were when I contacted them about the take down notice? ROFLRules and regulations...I pointed these flaws out to Ebay and Paypal more times than I can count over the past 3 or four years.But as always, money is all that matters and those scammers won't be stopped.If you get a refund then the seller will be punished by more than your feedback, only if the Paypal account he used was unable to provide the required funds.In the rare case the Paypal account disappears with the seller you will notice the refund comes from Ebay or Paypal but not from the seller's account.This is the only real buyer protection Ebay has on offer.The rest is just following the pressure of local laws, especially in terms of refund and warranties.Does not mean though a warranty for an Ebay item will be honored by a company....If you start selling on Ebay then one big requirement is to have a validated Paypal account.Also a real physical address - although this is only too often just taken as granted once you had a delivery to your nominated address.Either way you Paypal account's address and name must match what you used for Ebay.Means if things go really south both Ebay and Payl will have enough details to surrender you to the local law.In China however things are different, starting with space.An export business is highly subsidised as it brings in foreign currency.So you can just hire a dummy letter box in some office building for company purposes.All mail however will be directed to whatever real address you specified for your "company".Same for actual company grounds.A n awful lot of producing factories/companies over there get additional support by the government for supporting small export businesses.That means you, as a little Chinese Ebay power seller forward your orders to whatever factory produces or stores these thing in huge amounts.This company then does all the shipping for you.Becomes really clear once you try to figure out from where you Ebay shippment really came.There won't be any Ebay seller name on the address, same for whatever you found in the Paypal invoice.The guy can just sit in his lounge room and never actually touches any shippment at all.In mayn cases those sellers have good discounts and since small items ship for free out of China, no one complains about the extra work.Both Ebay and Paypal are well aware of those loop holes in China!But as with multiple accounts they look away and prefer not to act as long as the money keeps flowing.

Can you cheat on contests?

So I was browsing the contests and found an instructable that seemed kinda suspicious. The instructable itself was fine, but in the comments section I found about 8 users, all praising this "amazing", "genius" instructable, and when I checked the accounts, they were all made and favorited and commented on the post on the same day, and that was all of their activity. Oh yeah, the author also commented. I'm also guessing that they all voted as well. My question is, will this be overlooked, or will this author win possibly runner-up with their instructable for cheating? I hope that this will be noticed and will be thoroughly checked. Thanks,Zakbobdop

Powering a Salvaged Window Motor with 20v Battery (HELP!!!)

So earlier this month, I replaced the window regulator in my Honda Accord so I can sell it later on. After looking at the old regulator to see what was broken, I saw the motor component was perfectly fine, so I salvaged it for a future project! I do have a few ideas for what to do with this, but my main conundrum is how to power it when I have no 12V batteries lying around.I do have a Black & Decker Cordless Drill that uses 20v Li-Ion rechargeable batteries, and the shape of the battery is pretty compact. Its got 2 POS and NEG leads which you slide the contacts inbetween, and I can 3D print something to hold the battery in place for the project I intend to make with it. However, 20V is clearly overkill for this motor and that means I need to convert 20V to 12V. Does anyone have any ideas how to achieve this?

Serial/Console Interface for Video Brochure?

Hello All!  I recently acquired one of those cheap video brochures (the kind that loops a video on full volume until you want to dash it against a wall)... Anyways, I couldn't resist the urge to hack with it, so I pulled the enclosure apart to expose the electronics. Inside I found a magnetic switch, a USB mini connector with all pins wired (two power/two data), a motherboard with three ICs and a scattering of other components, and a rechargeable battery (seems to be LiPo) all wired up to a 5.5" display. I plugged the usb to my computer and it mounted as a drive labeled "MediaPlayer". Inside was the original video file that I replaced with one of my own videos in the same format. It now plays my video with sound. Where I am stumped is with the circuit board. I have not found any markings on the board itself, however it has some pins around the edge to which the switch and speaker were connected to (I'm guessing these may be GPIOs.....). There is also an unpopulated four pin header (to the right of the display connector) that looks like it may possibly be for another USB port. There are also four solderable connections (on the bottom of the left side of the board) that are labeled GND, HRP, HRL, and DET... I wasn't able to find any meaning for those, but is it possible to establish communication through that? Last but not least, the three ICs on the board seem to be a CPU, and two flash chips. The markings on the center one (which I'm assuming is the CPU) are: F1 E200 F8148DA 19H1  The second IC, to the right of the "CPU" is marked: hynix 812A HY5DU121622CTP-D43 KOR N7EAX553Q2 - also engraved with the letters JHY The final IC, left of the "CPU" is marked: hynix KOR HY27UF082G2M TPCB 604A M8SD53321 According to Google, the E200 refers to the all winner E200 SoC that supports UART, SPI and TWI... It also says that it runs OS Melis 2.0... I would like to hack into this system if possible and/or find a way to interface the LCD through SPI for my Pi Zero... Any help is greatly appreciated! Thanks! I included a couple of High Res photos to show the PCB (the display ribbon cable has been removed to show the third IC).

Expertise needed on melting and remolding plastic (PP, HDPE etc.) at home with hand made molds... there must be a way!

Hi, I want to make a rough casing for a project out of plastic of some kind. I tried the potato plastic instructables, but I'm not really happy with the result. So I attempted to melt down some plastic chips broken from old plastic casings (I think the plastic was polypropylene) in an old can on a barbeque (good as it was outside). This didn't work as I kept heating the plastic chips even when they became a bit soggy as I expected them to become much more liquid. This is because I hoped to 'pour' the molten plastic into a mold. Before this happened however the plastic caught fire. So, I was wondering if I heated them in a more sealed environment would the lack of oxygen make it possible to achieve a more molten consistency without the plastic igniting? Some plastics on consumer electricals have flame retardants... surely these would stop the plastic from igniting? If the plastic won't ever become liquid/molten, then I assume to mold it you have to have very high pressures (like commercial injection molding machines)... any ideas as to how to acieve these kind of pressures easily at home? I think with so much 'waste' plastic out there it'd be great to work out some easyish way of remolding it at home! Any help appreciated! Thomas

This pioneer receiver has been working for the last 30+ years.  I was using it in my wood shop and went to change the station, I spun the knob to go to a higher station and then the sound cut out and then the receiver turned off.  I then found that it blew the 2 amp fuse (the singled out one of the three used).  I replaced it and turned it on, the lights came on and the speakers put out a law *boooooooo* (low tone) and then the fuse blew again (about 3-5 seconds).   I am not great at diagnosing electrical issues but can replace something if instructed what needs to be replaced.  Please help.             Thank you.

USED TREADMILL BELTS - any good uses for them?

I fix gym equipment, so I throw away quite a few used treadmill belts. some of them are in good shape but just got too dirty to be useful anymore (friction problems).  seems a shame to throw out all that plastic, surely there are some good uses...can anyone think of some?  I just installed 8 today and hauled away the old ones. In the past i have screwed them to the bottom edge of garage & bay doors to act as an extra weather seal - helps prevent the cold air from rushing in those air gaps. the belts have a pvc topcoat and textile/woven fiber bottom. I wonder if any recyclers would take them...i hate dumping stuff in landfill. Wasnt sure where to post - resources, free stuff, Green....they would all apply really...

Arduino coding to allow separate push buttons to turn led on and off? Answered

I am new to the Arduino and have yet to use one. I understand a little about how to program the Arduino and would like to know more specifically about push buttons. I know that I will most likely have to use "edge detection" to determine when the push button is pressed. I don't want to have a push button turn an led on if pressed and if pressed again turn it off. I want to separate the on and off into two different buttons. When i push the first button it will always turn the LED circuit on even if i press it twice. When i push the second button it will always turn the LED circuit off no matter how many times it gets pressed. Is this possible, and if so how do i code it?

Maximum number of contests with 1 instructable? Answered

I have seen many instructables in the past be entered into as many as 3 contests at once, but now that I publish my first instructable, the maximum is 1? When did this change? I can't find any mention of it ever being less than three, in that case, is this a bug? I am really confused, as at no point was I notified of the change or made aware in any way, there isn't any reference to it in the forums or anywhere else I searched.

D.i.y. (plastic) nuts (for any kind of thread)

For emergencies or simple application: how to make your own nuts out of (p.e.t.)-plastic bottles:take a bottle (#1 plastic, preferably smooth, w/o imprinted patterns or design etc) > cut off bottom and neck > start cutting (scissors) > the resulting ´tube´ into a consistent (width, depending on desired usage), slightly diagonally, thus sort of ´peeling´ it > wrap the strip around the screw/threaded-part/etc you need the nut for twice (for a start) > ´melt´ the edges of the wrapped part = joining them (i use a little solder-iron) > this way the wrapped beginning of the strip wont come loose > ´brush´ with the solder-iron (or whatever other source of heat) over the wrapped part (w/o) burning holes in it > this causes the plastic to shrink and press down into the thread and adopt its shape > once set keep doing more wraps of the rest of the strip until you reach a desired diameter > now, again, join the edges of the wrap with heat, and afterwards brush again over the outside of the created ´nut´, so that the plastic shrinks down & compacts > after having cooled off: unscrew the ´nut´ with pliers > ready for useps this is just a simple sketch. got no camera to take photos. sorry. so, please, ask whatever if you got any question. and any kind of feedback is more than welcome. bowing.

So you wanna make Samus Aran's arm cannon eh?

Alright so I've decided this year for Halloween I want to be glorious Samus in her original suit glory. I'm just in the planning and blue print phase now. The bulk of the costume is going to be Eva foam. A stationary arm canon is cool and all, but what if I could get it to open up on the ends when i push a button? How cool would that be?I won't need a really beefy motor to move foam, and hopefully that motor wont require a huge power source, something that will fit inside the arm cannon somewhere.I can't find any video of HOW exactly the arm cannon opens up and functions but from this picture it could either A. opens up where the 4 outside plates separate from the main cannon to better reveal the pew pew part, this would require something to push out all four plates at the same time from the main cannon at a fixed distance. Not very much maybe half inch to an inch and be able to retract back flush against the cannon.B. the four plates simply rotate on a fixed axis.Ive crudely drawn what I would like the arm to do so you can see what I'm talking about.I've never dealt with motors before but I've seen amazing cosplays that have moving parts so I know it's possible. I'm more than willing to learn I just need to be pointed in the right direction.Any help with how to go about this would be greatly appreciated! :)

Where is the induction kettle or hot water system?

No modern kitchen these days is complete without at least a single induction cooktop.Convient to even place on the table to keep things warm but also nice to have 4 or 6 "hotplates" to cook on that are actually not getting hot at all.When it comes to efficiency induction cooking tops all others as no heat is wasted.Which brings me to the point...A single cooktop goes now often for well under 50 bucks.Although the base might end up slightly higher than a normal kettle I fail to see why we don't have induction kettles in our kitchen.Why wait 12 minutes to have the thing boil if you can do it cheaper and faster?Way more convinient too as there is no pesky contacts and heating elements anymore, no failure due to leaks either...But what really got me wondering is the hot water systems or heating options like prefered in Europe.Here you have a central "boiler" so to say and water circulates through valves into finned radiators, usually located under windows.We have oil filled radiators of this kind as free standing units that are now being phased out because they waste too much energy with their heating elements.Same story for just hot water :(On demand systems are getting more popular now outside Europe but still the common solution is to have a few hundret liters of water in a tank that is kept hot no matter how much of it we use.Be is gas or electric both types have their drawbacks and to get ahead of the corrosion that always kills them we now opt for expensive stainless steel tanks...Using induction it would be very easy to have a fully sealed tank and to actually only heat what needs to be heated without wasting too much energy.The "heating" element could be just a steel plate inside the tank with no connections to the outside.The gap between wall and element doubles to make the water circulate.And changing from a fixed timer to a temperatur control system to turn the induction element on and off is not hard either.Do you have an induction based hot water system, heater or maybe kettle already?Would love to see it...

Volume of gas from given weight of dry ice?

I'm rusty on basic chem. specifically, molarity, molecular weight... Dry ice, frozen CO2 is sold by the pound. I'd like to know by working formulas, how much volume a pound of dry ice will fill once it returns to gas. Carbon has molecular weight ~ 12.  Oxygen ~16.  But I don't recall what those numbers represent. One mole of gas occupies 22.4 liters, but how much does a mole of CO2 weigh?
